C:\Users\Admin>winget upgrade --all
Failed when searching source: winget An unexpected error occurred while executing the command: 0x8a15000f : Data required by the source is missing The fix is to run this as admin: Copy to Clipboard
Add-AppPackage -path "https://cdn.winget.microsoft.com/cache/source.msix."
After that you can try the original command and it should work. |
